Hexane on top of water?

Hexane on top of water?
Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!
